Class SVGSVGElem

      com.tinyline.svg.SVGGroupElem
          com.tinyline.svg.SVGSVGElem

public class SVGSVGElem
extends SVGGroupElem

The SVGSVGElem class implements the 'svg' element.

An SVG document fragment consists of any number of SVG elements contained within an 'svg' element.

An SVG document fragment can range from an empty fragment (i.e., no content inside of the 'svg' element), to a very simple SVG document fragment containing a single SVG graphics element such as a 'rect', to a complex, deeply nested collection of container elements and graphics elements.

Version:

2.2

Field Summary

static boolean	AUTOFIT The hint provided by the TinyLine application to choose the viewport location and size.
TinyString	baseProfile Describes the minimum SVG language profile that the author believes is necessary to correctly render the content.
TinyVector	cameraXform The additional "Camera" transform
int	preserveAspectRatio The 'preserveAspectRatio' attribute is used for adapting the content to devices with different display aspect ratios.
TinyString	version Indicates the SVG language version to which this document fragment conforms.
SVGRect	viewBox The viewBox specify that a given set of graphics stretch to fit a particular container element.
SVGRect	viewPort The viewport is the finite rectangular region of the canvas where actual rendering occurs.
TinyVector	viewXform The transform from viewBox (USER COORDS) to voewPort (DEVICE COORDS)
int	zoomAndPan The 'zoomAndPan' attribute defines the ability to magnify and pan.

Field Detail

AUTOFIT

public static boolean AUTOFIT

The hint provided by the TinyLine application to choose the viewport location and size. If the AUTOFIT is true (default value) then the SVG image fits the TinyPixbuf size.

baseProfile

public TinyString baseProfile

Describes the minimum SVG language profile that the author believes is necessary to correctly render the content.

cameraXform

public TinyVector cameraXform

The additional "Camera" transform

preserveAspectRatio

public int preserveAspectRatio

The 'preserveAspectRatio' attribute is used for adapting the content to devices with different display aspect ratios.

In SVGT the 'align' parameter can only be either 'none' or 'XMidYMid', the 'meetOrSlice' parameter can only be 'meet'.

Value: ( SVG.NONE | SVG.XMIDYMID_MEET )

Animatable: Yes

Init: SVG.XMIDYMID_MEET

version

public TinyString version

Indicates the SVG language version to which this document fragment conforms.

viewBox

public SVGRect viewBox

The viewBox specify that a given set of graphics stretch to fit a particular container element.

viewPort

public SVGRect viewPort

The viewport is the finite rectangular region of the canvas where actual rendering occurs.

viewXform

public TinyVector viewXform

The transform from viewBox (USER COORDS) to voewPort (DEVICE COORDS)

zoomAndPan

public int zoomAndPan

The 'zoomAndPan' attribute defines the ability to magnify and pan.

If disable, the user agent shall disable any magnification and panning controls and not allow the user to magnify or pan on the given document fragment.

If magnify, in environments that support user interactivity, the user agent shall provide controls to allow the user to perform a "magnify" operation on the document fragment.

Value: ( SVG.DISABLE | SVG.MAGNIFY )

Animatable: No

Init: SVG.MAGNIFY

Constructor Detail

SVGSVGElem

public SVGSVGElem()

Constructs a new empty SVGSVGElem.

Method Detail

public int createOutline()

Description copied from class: SVGGroupElem

Creates an outline of this node.

Overrides:

createOutline in class SVGGroupElem

getAttribute

public java.lang.Object getAttribute(int hattr)
